To all whom it may concern:

Be it known that I, J OHN V. Daemon, a citizen of the United states residing at l Veimar, in the county of Colorado and I a new and useful Adjustable Seat for Automobiles, of which the following is a specification.

This invention has reference to adjustable seats for automobiles, and is designed to provide means for the adjustment of the back of the front seat of an automobilewhereby the occupant may adjust the back of the seat to a comfortable position, or

even lay the back of the seat flat in order 7 to permit the assumptionof a prone position:

In accordance with the present invention the back member of the front seat is providedwith a segmental rack-like. and platewith a set screw capable of ready manipulatiomand a lock nut engaged by the screw and in turn engageable in the rack plate, so that the seat back is efiectivelylocked and firmly held 25 in any of numerouspositions of adjustment.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part :0 of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any, strict conformity with the showing of the drawings, but may 5 be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings :Figure 1 is an eleva- 0 tion of the locking means as applied to the back of the front seat of an automobile with the seat structure shown in front to rear vertical section. Fig. 2 is a section on the line 2-2 of Fig. 1 but showing one'side Fig. 3 is a section on the line 3-3 of Fig. 2 withthe cushions omitted. Fig. 4 is a perspective view of the rack plate. Fig. 5 is a perspective view of the lock nut used in conjunction with the rack plate.

1 Referring to the drawings there is shown in more or less diagrammatic outline a small portion of the body 1 of anautomobile, and

i also the showing includes the bottom 2 and 5 back 3 of the front seat. Ordinarily the back 3 is inrigid relation to the seat portion ADJUSTABLE sna'r it Specification of licttai s 'li Application filed February 13, 1915. "Ecriat l-Llifi.

2 of the front seat, but in accordance with the present invention the back 3 connected to the seat portion by a hinge 4., so that it may be moved into various degrees of inclination from anupiight to a horizontal position.

The seat portion 2 has side members 5 in fixed relation thereto. .Secured to opposite ends of the back 3 of the seat are segmental plates 6, one of which is shown. separately in Fig. Each plate has. one straight edge an angle flange '2' which "isap plied to the back 3 and secured thereto by fastening devices 8 which may consist of ordinary screws. The plate 6 defines 21 seg ment of approximately 90 "and adjacent to its curved edge it is formed with; a similarly curved slot 9 struck from the axis of the hinge 4: so that the platewill turn with the iti back 3 upon the hinge a! Between the curved slot 9 and the outer edge of the plate the surface of the plate is formed with a series of radial notches 10 which may be approximately coextensive with the length of the slot 9.

Each side member 5 adjacent to the point occupied by the upper end of the back 3 when in the ordinary upright position is recessed on the inner face, as indicated at 11, to receive a lag 12 projecting from one face of an elongated block 13 about mid way of the length of this block. The block 13 has a tapped passage 14 extending through the lug 12 and receiving a threaded shank 15 having On the outer face of each side 5 in position, corresponding to the location of the recess 11 is a bearing plate 17 through which the threaded stenfsr screw 15 passes, and which is engaged by the handle 16.

at one end a handle 16 by. means of which the threaded shank, con- 7 stituting a lock screw, may be man pulated.

The block 13 extends in opposite directions from the lug 12 and on one side is formed with a series of ridges 18 adapted to the notches 10 and on the other side has a plane extension 19 adapted to engage against the inner face of the segmental plate 6 adjacent to the, inner edge of the slot 9.

Mitt

[and

close to the upper front face ofthe back The side cushions represented at 22 are ordinarily not interfered with by the nut 13 and.

plate 6, since these parts need not be very thick, and do not occupy any such relative depth as indicated in the drawings, the roportions being exaggerated in the drawings in order to more clearly show the structure.

If it be desired to tilt the back 3 to a greater extent than the ordinary position, the handle 16 is turned to loosen the nut 18, so that the ribs 18 on the nut no longer forcibly hold in the notches 10, and the back ,may be pulled to any desired position, after rzhich on tightening the screw the nut is again clamped against the plate 6 wlth the lugs or projections 18 seated in their notches: 10 and the extension 19 hearing against the corresponding portion of the slot 9 and being seated in the recess 11. The same act1on of course occurs on both sides i of the seat, so that the back of theseat is firmly held in any adjusted position. If

for any reason the user of the automobile desires to assume the prone position the back 3 lowered to a level and all liability of catching anything between the back 3 and the sides of the body of the vehicle is prevcnted by the presence of the plates 6 which seat having relatively fixed seat and side portions and a back hinged to the seat portion, comprising segmental plates fast to opposite ends of theback and movablealon the side portions of the seat about the axis of the hinge'between the seat and back portlon, each of said plates being formed with a slot curved about the axis of the hinge plate 6, the lug 12 extending through the' ward and with the threaded and close to the outer edge of thegii late with the latter provided with a curved series of notches between the slot and said outer edge of the plate, a clamp screw mounted on each side of the seat and projecting through the slot in the corresponding segmental plate, and a nut for each clamp screw provided with an intermediate lug of non-circular shape'entering the slot'in the plate and having extensions on opposite sides of the lug, one of the extensions being formed with projections fitting the notches in the plate and the other extension being smooth and en gaging the plate on the side of the slot toward the axis of the hinge.

2. Adjusting means for an automobile seat having seat and side portions in substantially fixed relation one to the other and aback hinged to theseat portion, comprising segmental plates fast to theends of the back portion and each provided with a flange atone radial edge by which the plate is secured to tbe'corresponding end of the back of the seat, eaeh plate having a curved edge described about the axis of the hinge of the seat back and a curved slot adjaeent to said curved edge and between the curved slot and the curved edge provided with a curved 4 series of notches, an elongated nut having a central lug projecting through the slot in the plate with extensions on opposite sides of the lug, oneof which extensions is provided with projections adapted to the notches in the plate and: the other extension projecting "over the plate onthe side of the slot remote from the projections, and a screw provided with a manipulating means and carried bygtherspectiva side of the seat, said screw-extending through theside of the seat with the manipulating means outportion of the screw entering the nut.

In testimony, that I claim the foregoing as my own, I have hereto atlixed mysignature in the presence of two witnesses.
